If there are no cookies, it might throw a NullPointerException because u are
trying to access the variable (cookies.length) of an object which does not
exist. modify ur if statement to
if (cookies!=null && cookies.length)
I encountered the same problem for strings but never for cookies. This might
just solve the problem.
